Answer:

The ratio of the areas of these similar rectangles is 5:48.

Step-by-step explanation:

Let us convert area into fraction.

Ratio of the area of first rectangle to the area of second rectangle = $\frac{Area of first rectangle}{Area of second rectangle}$

= $\frac{25}{240}$

$= \frac{5}{48}$

Hence, the ratio of the areas of these similar rectangles is 5:48.

Gnoma [55]

Answer:

$x=-1$

Step-by-step explanation:

We have been given an equation $\frac{-2}{x(x+2)}=\frac{x+3}{x+2}$ . We are asked to find the solutions of our given equation.

First of all, we will cross multiply our given equation as:

$-2(x+2)=x(x+2)(x+3)$

Subtract $x(x+2)(x+3)$ from both sides:

$-2(x+2)-x(x+2)(x+3)=x(x+2)(x+3)-x(x+2)(x+3)$

$-2(x+2)-x(x+2)(x+3)=0$

Now we will factor out $(x+2)$ .

$(x+2)(-2-x(x+3))=0$

$(x+2)(-2-x^2-3x)=0$

$(x+2)(-(x^2+3x+2))=0$

Now we will factor by splitting the middle term.

$-(x+2)(x^2+2x+x+2)=0$

$-(x+2)(x+2)(x+1)=0$

$-(x+2)^2(x+1)=0$

Now we will use zero product property and solve for x as:

$-(x+2)^2=0,(x+1)=0$

$(x+2)=0,(x+1)=0$

$x=-2,x=-1$

Now, we will check for extraneous solutions.

We can see that $x=-2$ will make both denominators zero because our function is not defined at $x=-2$ .

Therefore, the solution for our given equation is $x=-1$ .

Answer:

x=-2

Step-by-step explanation:

-4(x-7)=36

divide both sides by four

x-7=-9

move constant to the right and change its sign

x=-9+7

calculate the sum

x=-2

A)

we will write the equation

$6x+5y=135$

B) x=10, we just replace the x and solve y

$\begin{gathered} 6(10)+5y=135 \\ 60+5y=135 \\ 5y=135-60 \\ 5y=75 \\ y=\frac{75}{5} \\ y=15 \end{gathered}$
